Abstract: PURPOSE:To automatically remove a solidified metal in the state of clogging or sticking on the inside of a nozzle hole by providing a lance feeding mechanism, water-cooling type nonconsumable blow pipe, oscillating mechanism, forwarding/backwarding mechanism and traversing mechanism in the maintenance of the hole through which metal is passed after a sliding nozzle and injecting nozzle are used. CONSTITUTION:A lance is inserted into a nozzle by the rotation of a motor 27 for a lance and with a rotor 47 for feeding a lance, dependent body 28 for feeding a lance and support 28 for a lance, advanced while blowing oxygen, initial holing is executed by advancing the lance so as to always contact with a raw metal and smelting during piercing. After the supply of oxygen is stopped after piercing, the lance is retreated by reversing the motor 27. After that, the blow pipe is made to coincide with the initially opened hole with a traversing device 3, next advanced with a straight motion motor 17 and made to coincide with the tip of a lower nozzle. After that, smelting is started from the through hole with preheating gas and cutting oxygen and oscillating motion from the upper part to the lower part is executed to prevent the resolidification of the row metal and deterioration of refractory materials.

Title: Spinning reel for fishing
Inventor: TSUTSUMI WATARU
IPC: A01K89/01
Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To produce a spool for the subject spinning reel capable of preventing such a backlash trouble that a wound fishline is released as it remains looped when reeled out and it gets intertangled with a running fishline after casting along with increasing a casting distance of an angling device by decreasing a reeling-out resistance as much as possible. SOLUTION: This spinning reel wherein a symbol (t) shows a distance between an outer periphery of the front end of a spooled fishline 4 and an outer periphery of a flange formed on the rear end of the spool 3 when the spool 3 is positioned at the rear end of an oscillate stroke, a symbol D denotes a diameter of the spool 3 at the front end of the fishline, a symbol (t') is defined as (t/2<=t'), a position O is one side end of the diameter D, the tip end of a virtual segment (D+t') draws an arc virtual line VL by using the position O as the center thereof, and on the above conditions the front end 31a of a fishline-winded barrel section 31 of the spool 3 is positioned outside the virtual line VL.  Even if the front end of a spooled fishline falls off in the form of a ring, the ring-shaped fishline never overstride the front side, and hence this prevents the fallen-off fishline from being intertangled with the running fishline after the angling device is cast.
